Abstract

Un dispositivo y un metodo para operarlo para aplicacion en un reactor de tubo vertical con un flujo descendente (descensor), tiene el proposito de asegurar el mezclado intimo del catalizador particulado solido con un fluido de reactivo. La distribucion homogenea del catalizador es debida al Uso de una placa 3 que tiene perforaciones 12. Dicha placa perforada 3 normalmente permite el paso de una porcion de la corriente de catalizador. La otra porcion sobrefluye los bordes de la placa, fluyendo en la forma de una cortina anular 16, cerca de la superficie interior del tubo circundante 1 del dispositivo. Despues de pasar mas alla de la placa perforada 3, el flujo de cortina 16 se somete a una deflexion producida por una pantalla anular 7, a ser mezclada con la corriente originada desde los agujeros 12 en la placa perforada 3. Una carga de hidrocarburo se inyecta por debajo de la placa perforada 3, formando un cierto angulo con respecto a la direccion, de flujo descendente del catalizador, por medio de las entradas 9 distribuidas uniformemente alrededor de las secciones transversales del tubo circundante 1. Despues de la region de mezclado 8, el diametro del dispositivo, cuando es mas pequeno que el diametro del reactor de tubo asociado, se expande ligeramente.
